Answer:
Di positive ion.
Step-by-step explanation:
Ionization energy is the energy required to remove the most loosely bound electron from an isolated gaseous atom.
As per the data given, there is not much energy difference between first and second ionization energy.
Hence the atom will lose two electrons easily.
However as there is very high difference between second and third ionization energy so it will not lose third electron easily.
Hence the possibility of formation of dipositive ion is most for the given atom.
The common ion will have two positive charge.
